Simulation of boron rejection by seawater reverse osmosis desalination

yes / Boron is a vital element for growth of creations, but excessive exposure can cause detrimental effects to plants,
animals, and possibly humans. Reverse Osmosis (RO) technique is widely used for seawater desalination as well
as for waste water treatment. The aim of this study is to identify how different operating parameters such as pH,
temperature and pressure can affect boron concentrations at the end of RO processes. For this purpose, a
mathematical model for boron rejection is developed based on solution-diffusion model which can describe
solvent and solute transport mechanism through the membranes. After a wide and thorough research, empirical
correlations developed in the past are filtered, adopted and calibrated in order to faction with reliability as part of
the solution-diffusion model of this work. The model is validated against a number of experimental results from the
literature and is used in further simulations to get a deeper insight of the RO process. The general findings of the
boron rejection model are supporting the case that with increasing pH and operating pressure of the feed water,
the boron rejection increases and with increasing feed water temperature the boron rejection decreases.
